I have done a web page with CSS styles in the HTML file. Still when I try to send the file as an attachment as text the styles don't render well, for example divs have borders and links doesn't work at all. I try to send a newsletter.

Hi,

Would you please attach a screenshot to help us understand the issue? If your account is not verified to attach images, please share the screenshot to us via sending it to GBSD TN Office Information Collection ibsofc@microsoft.com. (The email subject should be the thread link)

Thanks,
